Question

Express the following quantities in SI units: (a) 10.2 in./min

(b) 4.81 slugs
(c) 3.02 lb
(d) 73.1 ft/s2
(e) 0.0234 lb s/ft

Answer 1

Quantities in SI units: 10.2 in./min becomes 0.00431733 m/s, 4.81 slugs becomes 70.214 kg, 3.02 lb becomes 1.369 kg, 73.1 ft/s2 becomes 22.281 m/s², and 0.0234 lb s/ft becomes 0.0032152 kg s/m.

Step-by-step explanation:

To express the following quantities in SI units, we need to apply conversion factors between the units mentioned in the question and the corresponding SI units.

1. 10.2 inches per minute (in./min) to meters per second (m/s):
   10.2 in./min × 0.0254 m/in. × 1 min/60 s = 0.00431733 m/s
2. 4.81 slugs to kilograms (kg):
   4.81 slugs × 14.5939 kg/slug = 70.214 kg
3. 3.02 pounds (lb) to kilograms (kg):
   3.02 lb × 0.453592 kg/lb = 1.369 kg
4. 73.1 feet per second squared (ft/s²) to meters per second squared (m/s²):
   73.1 ft/s² × 0.3048 m/ft = 22.281 m/s²
5. 0.0234 pound second per foot (lb s/ft) to kilogram second per meter (kg s/m):
   0.0234 lb s/ft × 0.453592 kg/lb × 1 m/3.28084 ft = 0.0032152 kg s/m
